 T&I DVD ROM 11.2
HVAC Basics: Residential Heating and Ventilation
Shopware
LAWRENCEVILLE, NJ, FILMS MEDIA, 2008.
DVD ROM — This program illustrates several different types of heating systems, including forced-air gas furnaces, high-efficiency
furnaces, and hot air systems. Different types of ignition and fuels are covered, along with the major elements of gas furnaces, including
solenoids, burners, manifolds, heat exchangers, and more. Air flow components such as supply and return plenums, air filters, and split
capacitor motors are also explained, in addition to thermostats, pilot safety switches, and gas valves. Viewers will get a look at the
automated service centers at the heart of many modern large office buildings, which maintain climate control using high-tech sensors
and adjustment systems. 24 minutes.

T&I DVD ROM 11.3
HVAC Basics: Residential Air Conditioning
Shopware
LAWRENCEVILLE, NJ, FILMS MEDIA, 2008.
DVD ROM — This program, summarizes air conditioning operation and service. Typical systems for cooling or dehumidifying residential
environments are covered. Details on condensing units and their components—including the condenser coil, compressor, motor, fan,
and accumulator—are illustrated along with typical outside housings and insulation materials. The three methods of heat transfer—
conduction, convection, and radiation—are outlined, along with the difference between high side and low side pressure systems. The
refrigeration cycle is demonstrated, as are different types of compressors, such as scroll, reciprocating, and piston. Heat pumps,
electrical controls, evaporators, and sight glasses are explained. 21 minutes.
